Luck has nothing to do with it.  Luck is preparedness + opportunity.

 

If it isn't working, then you aren't understanding why.  The why could very well be you're missing the players to execute.  You have to understand why it's failing in order to fix it, or change/create/modify/adapt to fit what you have until you do get the right ingredients.  You change the players to get the fit, or fit to the players.  Where you fail is where you're missing the pieces and unwilling to change them, or unwilling to change to best use your pieces.

 

Hubris is the most common reason for such failure.  If you aren't willing or simply fail to identify the problems, you can't possibly fix them.
